This toolbox was developed to provide a summary of information that local agencies should be aware of to prepare for connected and autonomous vehicles (CAVs). The main goal of this toolbox is to assist local agencies in preparing for CAVs in the short term - 5 to 10 years. Since local agencies are not generally expected to have the resources to become test beds...

The National Academies–TRB Forum on Preparing for Automated Vehicles and Shared Mobility was officially launched in early 2018 to facilitate evidence-based research needed to deploy these technologies in a manner and timeframe that informs policy to meet these long-term goals. The Forum has held five meetings since then, promoting discussion among its...

This study explores where automated decision-making systems impact transport activity, and how. More and more transport activity is influenced by algorithms. Automated decision-making is taking a hold in areas from health care and housing to media and mobility. In transport, algorithms are a core feature for services from public transport scheduling to routing...

En dépit de données canadiennes abondantes sur les associations entre aménagement urbain et comportements liés à la santé, nous savons peu de chose sur les associations entre aménagement urbain et problèmes de santé. Cet examen de la portée est destiné à offrir une synthèse des données tirées d’études quantitatives ayant examiné la relation entre l’...

Despite the accumulating Canadian evidence regarding the relations between urban form and health behaviours, less is known about the associations between urban form and health conditions. Our study aim was to undertake a scoping review to synthesize evidence from quantitative studies that have investigated the relationship between built environment and chronic...

State highway agencies (SHAs) continually face important financial decisions when planning a new or reconstructed highway. For example, what is the initial investment for the highway? How much is needed periodically to maintain the highway in good pavement condition? What materials should be used to build the pavement? The answers to these questions may require...

This document is the project report for the Connected Vehicle Infrastructure—Urban Bus Operational Safety Platform Project also known as the Enhanced Transit Safety Retrofit Package (E-TRP) project. The report describes the project’s background and purpose, summarizes its activities and results, includes results from an independent evaluation, and...

Since Safe Routes to Schools (SR2S) methods first gained prominence in the 1990s, researchers and practitioners have been working to determine best practices that can yield improvements in two areas: improved health and increased ATS participation. Many of these projects and programs have focused on the provision of physical infrastructure that can improve...

This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we...
